10 Claims. (01420-0) This invmtion relates to combination pencil andfountain and for an object to provide an instrument of the type whereineither of. the instrumentalities may be projected 'into 5 writingpositionand that while the instrument is heldin writing grasp in thehand.

. A further object of .the invention is to provide in the instrument ofthe type a pen movable longitudinally within a barrel in such .mannerthat its extreme point projectsslightly through a perforation in a capat the endjof the barrel, the major part of the pen remaining within thestructure. t

T A further object of the invention ,is'to provide .an instrument of thetype having an extremity conoidal in shape through the apex of which maybe projected electively a pen or a pencil as the writer progresses inits use which are the basic features of my invention.

A further object of the invention is to provide an instrument of thetype having a barrel whereinis mounted slidably a pen carrying an inkres-' ervoir therewith which said pen is projected to writing positionwith its point only extending slightly beyond the conoidal end of thebarrel structure with means for projecting the lead of a pencil alsobeyond the point of the conoidal structure.

A further object of the invention is to provide within a singleinstrument a plurality of pens either of which may be projected towriting position independently of the other and a plurality of pencilsthe lead of which may be independently projected to writing positionwhich is a generic feature of my invention.

A further object of the invention is to provide a pen structureincluding a pencil having a cap thereon remaining fixed upon thestructure during the operation of both pen and pencil which extendthrough said cap into operative position, eliminating the use of a.removable cap as customarily found in all such structures.

A further object of the invention is to provide in an instrument of thetype a barrel having a cap formed as a conoid having a small perforationin its apex with a structure within the barrel carrying a pen the pointof which is properly contoured to extend through the perforation in theapex of the conoid with means at the opposite end of the barrel foractuating the pen and its associated structure.

The invention further comprises a body having one or more barrelsas apart of such structure within which barrel or barrels are locatedslidable members each carrying a pen and an ink reservoir, the barrelbeing provided with a conoidal cap, perforated at or adjacent to itsapex providing for the passage therethrough of the pen or pens to extendmerely to such an extent as to be in writing poation, the major part 5of the pen being still retained within the conoidal cap with one ormoretubes associated with the barrel or' barrels, each of said tubes beingprovided with a structure adapted to retain the lead of a pencil andmeans for movingthe structure longitudinally of the barrel to projectthe lead ofthe pencil through a perforation ator adjacent to the apex ofthe conoidal cap and into writing position whether the pen be in writingposition or not.

At its opposite end the barrel is provided with a sleeve 32 and a cap 33mounted thereon which provides space which may be employed for apurposedesired; as for instance for containing the extra leads 34.

The term lead as employed in this specifi-;

cation and claims is' intended to convey such rigid writing medium as isordinarily found, in lead pencils or the like irrespective of the coloror actual material from which it is constructed.

Within the barrel to a block as is. mounted to slide and for sliding theblock a wire 35 is provided having substantially parallel legs joined bya cross bar 31. Upon this cross bar 311a disk 38 carried by the sleeveis provided so that as the sleeve 32 is screwed downwardly upon thebar-'- rel the disk 38'bears upon the cross bar 31, de-

omitted between the member 49 and of the opening 41.

pressing the legs of the wire 35.

To resist such movement-a spring 39 is employed bearing at its upperendagainst a disk 40 and at its lower end against a disk 4| seateduponan annular shoulder 42 in the barrel.

when, therefore, thesQeve 32 is screwed downwardly from the positionshown at Figure 2'to the position shown at Figure 3, the block 35 hasmoved downwardly as shown in those figures.

To insure the proper function of the wire 35 to move the block the endsof the wire are bent inwardly to form hooks 43 hooking into the block.

This block 35 is provided with a reduced neck 44, with a passage 45therethrough and a collapsible andresilient bag 46 mounted upon thereduced part.

The block is also provided with an axial opening 41 in which is mounteda sleeve 48. Within this sleeve 43, which may be omitted if desired, thepen and feeding organization are inserted. This comprises a member 49,(see Figure 4) having a passage 50 which is eferably filled with anabsorbent material s pported in any approved marmer as by the pin 52.This absorbent material is in communication with the passge 45 leadingfrom the ink reservoir 46 so that the ink contained within the reservoiris absorbed in the absorbent material 5|. Member 49 is provided with apassage 53 which is also in communication with the ink supply with anoffset or lateral pas-..

sage 54 which communicates from the absorbent material to the passage53. 3

After this has been inserted into the block 35, the pen 55 of any usualand well known type may be insertedbetween the member 49 and the sleeve43 when employed, or if the sleeve 48 is the walls Instead of making themember 49 simple as shown at Figure 4, a modification as shown atAssociated also with the pen structure is a pencil structure. .Thiscomprises a pusher wire 58 having a sleeve 59 of proper contour toreceive and retain a lead 80. For moving the lead to operative positiona slot Si is provided in the side of the barrel and the wire is providedwith an angular part 30' which extends to or beyond the surface of thebarrel as indicated at Figures 1 and ,3. The movement of the wire in thedirection indicated by the row in Figure 3 will move the lead 50 so thatit will be projected through the perforation 52 to the position shown atFigure 1.

For filling the reservoir 46 aperforation 63 is provided through thebarrel through which any slender instrument may be inserted. A spring 64is supported by means of a resilient ring 65 (see Figure 21) and extendsdownwardly along the side of the bag 46. This spring is provided withthe return bend 55 whereby a part 66 is provided which will not followthe curvature of the spring 64 when the instrument is inserted asindicated in dotted lines at Figure 3, but will compress the bagas alsoindicated in dotted lines at that fig-' ure, The resiliency of the bagwill, of course, tend to expand the bag to induct ink within the bagthrough the structure in the usual well known manner, the cap 3| beingpreviously preferably removed for that purpose.

In the type shown at Figures 9 to 11 inclusive, two barrels 31 and 68are provided, eachsimilarlf accommodating a bag 69 and 10 whichcommunicate with the pen through substantially the same structure asshown at Figures 2 and 3. Instead, however, of moving this pen structureby means of a threaded sleeve the cap H is fixed relative to thestructure of the barrels 61 and 68, slidable independently relativethereto and to the conoidal cap I2 so that either the pen 13 or I4 maybe electivelyprojected by simply pushing longitudinallyupon the barrel61 or 68 which carries the pen which it is desired to use. It is, ofcourse, contemplated that inkof diiferent colors shall be employed inthe two bags 59 and I0, and that therefore the projected pen will writethe color of ink carried in that organization. It is obvious that as thestructure shown at Figures 9 to 11 inclusive is held in the hand inwriting position either of the barrels 51 or 58 may be moved to writingposition, thereby changing from one color to another without changingthe position of the pen structure in the end, and that substantiallyinstantaneously.

The conoidal cap I2 is made slidable upon the barrels 61 and 68 asindicated by space at Figure 10. When it is desired that both pens shallproject simultaneously the cap I2 is moved to close the space 15,whereupon both pens have their points extended beyond the conoidal capmay be closed by any type of block II. It is contemplated that thisblock "shall be a type to serve as an eraser and is brought into use bythe removal of the cap II.

The bags and It are nlled by the use of the same type of filling deviceshown at Figure 21, comprising, the ring I, spring 84 and its associatedparts. i

In the angles provided by the associated barrels l1 and I smallerbarrels II and II are provided. These barrels II and II are providedwith slots .0 and 8| through which extend respectively the members itand 88. These members I! and It are associated with wires It and." whichslide longitudinally within the barrels I! and It and are each providedwith a sleeve II which receives and retains a lead .1.

Whiletwo of these barrels l8 and II with their lead and accompanyingmechanisms have been shown it is obvious that either or both may'beomitted. At Figure 16 a single perforation I! is shown to accommodateone lead the other being omitted, while at Figure 17 both leads areindicated as omitted openings 8| and ll being provided to accommodateboth of the pen points. Joining these openings ll and II orotherwisecommunicating therewith is a vent OI which relieves internal suction. i

To provide for properly sliding the cap 12 or the barrels 01 or 68relative to the cap 12, the cap is provided with knurled portions 0|shown more particularly at Figure 14.

To, provide for maintaining the two barrels in operative relation toeach other while being moved independently one is provided with achannel chamber 82 and the other with a cooperating part 93 as shown atFigure 13. These members 92 and 93 extend from the upper end of the penlongitudinally to about the point indicated at it in Figure 11. Bystopping at this point a certain amount of resiliency is providedbetween the barrels 61 and I whereby the barrels tend to spread when theconoidal cap 12 is pushed forward in disengaging use of pens andtherefore exert a tension upon the cap to maintain the cap in positionwhen the cap is so located.

As an alternative a dove-tailed connection 03 is shown at Figure 19. Asshown at Figure 13 the barrels 81, II, II and I! each standindependently and in full sight of the user. In the type shown at Figure19, however, all are formed within the moulded or otherwise producedstructure whereby a device is produced which is substantially ellipticalin transverse section all of the barrels being contained within theellipse.

Figure 18 is in view partly in side elevation and partly broken away ofthe type shown intransverse section at Figure 19 and discloses theconfiguration oi the barrels in that type.

In operation, the single type as shown at Figures 1 to 3 inclusive isemployed by manipulating the cap 33 to actuate the sleeve 32 and therebydepress the spring of the pen structure forcing the point only of thepen through the perforation 51 as shown at Figure 3. The advantage thusattained is that substantially the entire pen is covered and the fingersof the user do not become smeared with ink as in the use of ordinarypens. Also when the pen is retracted to the position shown at Figure 2it is completely enclosed and it is not necessary to remove and replacea cap at each use of the pen, the pen being sumciently protected andcovered when withdrawn within the cap 3|, without any additional orauxiliary cap. The pen thus extended'may be employed in the usual mannerand whenever it is found desirable the pencil may be convenientlymanipulated with the structure still in writing position so that changemay be instantly made of the pen through the conoidal cap in the sameposition as described in regard to the use of the simpler type shown atFigure 3. Both of such pens may be simultaneously extended, when sodesired, and either brought into use simply by rotating the structure inthe ringers. The same 15 protection is afforded-by the cap 12 asdescribed in regard to the copy 3| oi the singlebarrel type. In thestructureshown at Figures 9 toll. in-- elusive where two pencils arelikewise disclosed, it

is contemplated that leads within the meaning 20 above described ofdifferent colors shall likewise be employed and either may, therefore,be usedselectively or both may be advanced simultaneously and by mererotation may be brought into use. These may be one or both extended,while I one or both of the pens are also extended so that with thedevice as shown at these figures, a complete writing instrument capableof writing in two colors of ink and twocolors of pencil, with nomanipulation whatsoever, is afforded.
